REVOLVING OR TRAVELING BEATER-COVE'R.

. SPECIFICATION forming part of Letters Patent No. 699,347, dated May 6, 1902.

Application filed June 8,1901.

To all whom it may concern:

Be it known that we, JOHN E. RAeAN and JOHN S. ROSENTHAL, citizens of the United States, residing at Graceville, in the county of Bigstone and State of Minnesota, have in vented certain new and useful Revolving or Traveling Beater-Covers, of which the fol lowing is a specification.

Our invention isa revolving or traveling beater-cover consisting of a strong piece of canvas or other suitable pliable 1nateria1,slats, straps, and buckles or loops and strings, said combination adapted to cover the heaters of a threshing-machine and to be secured thereto.

In the accompanying drawings, Figure 1 is a sectional elevation of so much of the thresher as is necessary to show the connection of the boaters and our beater-cover. Fig. 2 is a perspective view of the beater-cover adapted to be secured around the beaters by straps and buckles or loops and strings. Fig. 3 shows a modified form in which loops and strings are used and the manner of passing the strings through the loops.

Our invention is described as follows and may he used on all beaters, single or double, in any threshing-machine using boaters as an attachment for threshing flax or any substance that is inclined to rope or wind around the boaters.

1 represents a part of the thresher-box.

2 is the feed-chute; 3, the feed-wheel or feed-cylinder; 4t, a projection with an extension-board to give the material being threshed the proper direction, so that it will light on and pass over the threshing-floor 5.

6 represents the heaters.

7 is the fan-wheel. This fan-wheel may be situated in any proper positionin the thresher.

8 is the air-chute.

9 is a longitudinal sectional view of the beater-cover around a pair of the boaters. There may be more than one pair of heaters in a threshing-machine, and when there is we use this cover around every pair of heaters used.

Our beater-cover 9 consists of a piece of strong canvas 10 or other suitable pliable material. This canvas is preferably rectangular and oblong in shape-that is, it is somewhat longer than it is wide. Running across the inner face of this canvas from one edge Serial No. 63,712. (No ms.)

to the other are slats 11. Three of these slats are shown in the drawings; but there may be more than three used, if necessary. These slats are made of steel, hard wood, or any suitable material, and like slats may be also used on the outer face of the canvas. On the inner face of the canvas and secured to the inner face of the same and theinner faces of the slats are straps 12. These straps are secured to the canvas and slats by strong brass rivets 13. At the headend of each of these straps is a ton gee-buckle 14:, and the tail ends of these straps are provided with perforations 15, so that the cover may be securely buckled around the beaters. The canvas extends beyond the perforated ends of these straps,,and near the tail end of said canvas and on the inner. face thereof are secured small straps 16, and in the tail ends of these straps 16 are perforations 17. To the head end and rear face of the canvas are secured straps and buckles 18, corresponding to the straps just described. r 19 of Fig. 3 shows the back part of the head end of the cover, and instead of being provided with straps and buckles, as shown in Fig. 2, it is provided with loops 20, which are secured to the canvas, and at each end of the canvas and on a line with the loops 20 are secured at oneend strings 21. y

22 represents the inside and tail end of the canvas, having secured to its inner face loops 23, which correspond with loops 20.

When the cover is put around the boaters, the straps 12 are buckled into the buckles 14-. Then the straps 16 are buckled into the straps and buckles 18. Thus the cover is securely fastened around the heaters but when we use straps, loops, and strings instead of the straps 16 and straps and buckles 18 the loops 20 and 23 are drawn together on a line, so that the two strings 21 may pass through the loops and be tied in the middle, and thus hold the canvas more securely on the boaters. These loops 2O 23 and strings 21 are made of strong rawhide, but may be made of other suitable material.

The extreme tail end of the canvas is left loose, so as to cover the straps 16 and straps and buckles 18 or the loops 2O 23 and strings 21, the heaters always running in such a direction as not to double the tail end of the canvas back.

The advantages of our revolving or traveling beater-cover are briefly as follows: It is obvious that the cover, whether made of canvas, leather, or other flexible material, affords a modified resistance less likely to injure the flying grain impacting against the surface than wood or metal, and that the continual travel of the cover will continue to present new surfaces for wear, and thus prolong the useful life of the device. The traveling cover will do its work better than the stationary cover and without bunching up the material being threshed, as the stationary beatercovers do. We have found the traveling beater-cover a great success in threshing flax or any other grains that have a tendency to rope or wind around the beater. Our traveling beater-cover is more easily attached to the beater of a thresher and can be attached in less time than any other beater-cove r, and it runs more easily and smoothly than any other beater-cover we ever saw or used. It delivers the material more evenly to the shakers than any other make of cover and separates the grain from the straw better and more regularly, and it runs steadily without jerking.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A beater-cover for threshing-machines, consisting of a pliable piece of material, preferably rectangular and oblong in shape; slats secured to the inner face and crosswise of the said pliable material; straps perforated at their tail ends, and provided with buckles at their head ends, and secured to the inner face of the pliable material, and the inner faces of the slats; perforated straps secured to the inner face and tail end of the pliable material; straps and buckles corresponding with said last-mentioned straps, and secured to the outer face and head end of said pliable material, substantially as shown and described and for the purposes set forth.

2. A beater-cover for threshing-machines, consisting of a pliable piece of material, preferably rectangular and oblong in shape; slats secured crosswise and on the inner face of said pliable material; straps secured to the inner face of the pliable material, and inner faces of the slats; said straps being provided at their tail ends with perforations, and at their head ends with buckles; said heatercover adapted to be secured around a pair of boaters, and further around said heaters by suitable means, substantially as shown and described and for the purposes set forth.

3. A traveling or revolving beater-cover for threshing-machines, consisting of a pliable piece of material, preferably rectangular and oblong in shape; slats, or other suitable material to answer the same purpose, secured to the inner or outer, or both faces of said pliable material, and across the same; straps perforated at their tail ends, and provided with buckles at their head ends, and secured to the inner face of the pliable material, and the inner faces of the slats; perforated straps secnred to the inner face and tail end of the pliable material, at its head end, and the inner faces of the slats; perforated straps secured to the inner face and tail end of the pliable material; straps and buckles corresponding with said last-mentioned straps, and secured to the outer face and head end of said pliable material, substantially as shown and described and for the purposes set forth.

4. A traveling or revolving beater-cover for threshing-machines, consisting of a pliable piece of material, preferably rectangular and oblong in shape; slats, or other suitable material secured crosswise the inner or outer, or both faces of the pliable material; straps secured to the inner face of the pliable material, and inner faces of the slats, or other suitable material used; said straps being provided at their tail ends with perforations and at their head ends with buckles; said traveling or revolving beater-cover, adapted to be secured around a pair of beaters, or a single beater on threshing-machines, and further around said beater bya suitable means, substantially as shown and described and for the purposes set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
